Jeff Suzuki (who teaches Math at Boston University) wrote this about the humble but powerful log(arithm)
Note: the tune to this song is the same as the slinkie song, or to the log song from Nickelodeon. All of the mathematics in it is correct.
To multiply, add
This makes it not bad
For nth roots you need to divide
Subtract for quotients
And for exponents
The power comes down outside!
It's log! It's log!
It's integral 1 over x!
It's log! It's log!
As natural as breathing or sex!
(Repeat until hit with a ln)
Now, I present the Log song from the Ren and Stimpy Cartoon from Nickelodeon in the 1990’s:
What rolls down stairs
alone or in pairs,
and over your neighbor's dog?
What's great for a snack,
And fits on your back?
It's log, log, log
It's log, it's log,
It's big, it's heavy, it's wood.
It's log, it's log, it's better than bad, it's good."
Everyone wants a log
You're gonna love it, log
Come on and get your log
Everyone needs a log
log log log
LOG FROM BLAMMO
Just some fun with logs and a really catchy tune!

First of all, thanks for the link - Scrap Paper.
Second, about logarithms. The logs of sin and cos are negative so the old navs added 10 to make positive numbers. Still you were dealing with a decimel point and had to rember to drop the the 20s and 30s etc. Why do you think the method of multplying by -100,000 was not used instead?
Greg Rudzinski posted a sin, cos, log table that is very easy to use. I have done sight reductions from the old Bowditch and other old texbooks and the -100,000 log table seems SO EASY compared to the +10 tables. Do you know if anyone used simalar tables in the 19th C. or had no one thought of it? I find that doing time sights with the sin, cos, log ( times -100,000) is fun.
I have learned to love logarithms.
